How to write bigint (timestamp in milliseconds) value as timestamp in postgresql

Question

I\'m trying to store in timestamp with timezone field my value. It is in milliseconds from 1970.

select TO_CHAR(TO_TIMESTAMP(1401432881230), \'DD/MM/YYYY HH24:MI:S

Answer 1

Okay, I understood. My INSERT should looks like:

INSERT INTO events (timestamp) VALUES (to_timestamp(TO_CHAR(TO_TIMESTAMP(1401432881222 / 1000), 'YYYY-MM-DD HH24:MI:SS') || '.' || (1401432881222%1000), 'YYYY-MM-DD HH24:MI:SS.MS'))

I'm converting bigint-timestamp with milliseconds to text with required format ('YYYY-MM-DD HH24:MI:SS.MS') and pass it to to_timestamp function.
